SUMMARY

The discussion centers on the implementation of infinity in modern mathematics, highlighting its presence in various mathematical constructs such as extended real numbers, cardinal numbers, and projective reals. Participants argue that while infinity is often treated as undefined in elementary algebra, it is indeed utilized in advanced mathematical concepts like limits and meromorphic functions. The conversation emphasizes the need for a clearer understanding of different types of infinity, such as projective infinity and Aleph numbers, to avoid confusion in mathematical discourse. Overall, the consensus is that infinity can and should be integrated into algebra with proper definitions and properties.

PREREQUISITES
  • Understanding of limits in calculus
  • Familiarity with extended real numbers
  • Knowledge of cardinal and ordinal numbers
  • Basic concepts of algebra and functions
NEXT STEPS
  • Research the properties of projective numbers and their applications
  • Study the concept of limits and how they relate to infinity
  • Explore the definitions and uses of Aleph numbers in set theory
  • Investigate the role of infinity in complex analysis, particularly in meromorphic functions
USEFUL FOR

Mathematicians, educators, and students interested in advanced mathematical concepts, particularly those exploring the role of infinity in algebra and calculus.

What I meant to say, and I apologize if this was actually unclear, is that sometimes the currently accepted definition is not the final word in the definition. Perhaps a better, more useful definition is possible. I think I'm done with this thread.

To be fair, there are also uses (convergence of infinite products, for example) where 0 is not considered a finite number. But the usual definition of finite number, to me, is "between two integers" which of course includes 0.

Final word??
THIS is what you actually said:
How can you call 0 finite?

Have you ever given it any thought, or are you just parroting conventional wisdom?
This is very clear. Here, you are advocating the ideas that:
1. It is FALSE to call 0 a finite number
and
2. That the evil "establishment" somehow have brainwashed people into thinking that 0 might be a finite number.

There is nothing ambiguous in what you wrote, and your last post is just a shameful cop-out.
Perhaps a better, more useful definition is possible.
As in your previous empty blather?
I think I'm done with this thread.
how considerate of you.

This is the most bipolar thread I've ever seen, intensely funny and depressing. Everyone knows more about math than the mathematicians. Especially CS people (no offense to those who actually take the time to understand the concepts they are abusing, if you exist). The last time I read a post by CSProf he was trying to convince me that the reals are countable!

Hasn't people yet learned that mathematics is not science and we somehow have "arbitrary definitions"?

Do they know the definition of what definition is?

I think we defined things way they are because... because... damn I cannot remember. But I am sure there's a reason! And I am sure they will keep discovering reasons why it should be wrong! [/sarcasm]

I suggest that we adopt the following rule:
\frac{\Infinity}{\Infintity}=1

You mean as in

3237+ 2343= 1

213/234= 1

e3243= 1?

Certainly would simplify arithmetic!
